MULTIPURPOSE FRONT-END BOARD TO CHARACTERIZE SOLID-STATE SENSORS FOR PARTICLE DETECTION

摘要

A multipurpose front-end board for solid state sensors is described. In particular, the board is optimized for fast timing particle detection or for characterization and test of silicon and diamond detectors that produce a fast but small current signal at the passage of a particle. The multipurpose front-end board includes a sensor pad configured to receive a solid state sensor to be characterized, distribute a bias potential, and read out the current signal produced by the sensor. The board also includes an amplifier configured to read out the current signal from the sensor pad and convert the current signal to an output voltage signal and a discriminator configured to receive the output voltage signal from the amplifier. A threshold voltage of the discriminator can be controlled by a potentiometer, and the board includes at least one output port to provide data for characterization of the sensor.
